46 Gas Detection Expert advice and precision solutions for methane detection
nanoplus’ lasers for methane (CH4) detection are widely used in a variety of applications particularly in process optimisation for combustion control, greenhouse gas detection, leak testing in gas pipelines and breath analysis.
Tunable diode laser spectroscopy enables CH4 measurement up to ppb levels in real time and in situ. The nanoplus lasers are ideal for harsh industrial applications because they offer long-term stability and need little maintenance.
nanoplus lasers operate at a variety of wavelengths to target the range of vibrational-rotational bands of methane; 1654 nm and 3270 nm are generally perceived as the wavelengths most suited to detect methane. These as well as other customised wavelengths for methane detection are available from nanoplus.
When you choosing wavelength, you need to consider how the product is set up, as well as the locality and nature of the measurement. These are signifi cant factors when determining the optimum wavelength for any specifi c application. It is very advisable to refer to the Hitran Database (high-resolution transmission molecular absorption database) to further evaluate your choice of wavelengths. The application experts at nanoplus are more than capable and happy to advise you about the most suitable wavelength for your specifi c application – you simply need to tell them the wavelength you need with an accuracy of 0.1 nm!

New gas sensors for the semiconductor industry
In the fi rst quarter (Q1) of 2022, Sensorix has announced the expansion of its sensor range for hydrides and hydrogen chloride, which are widely used in semiconductor manufacturing.
One of the riskiest industrial sectors in which many hazardous gases are used is the semiconductor industry. The storage, distribution, or use of such gases in production processes not only poses potential risks to the health and safety of employees, but also threatens the existence of the business. Therefore, their monitoring in industrial processes such as the production of semiconductor materials is highly crucial.
To ensure industrial safety, a reliable system for detecting low concentrations of toxic and dangerous gases is needed. Because many semiconductor processes use hydrides like arsine, phosphine or silane, its presence and concentration have to be monitored. This requires high sensitivity, fast response, and good selectivity of the gas sensors. “The increased demand of electronic components during the Covid-19 pandemic requires reliable gas detection for safe and uninterrupted semiconductor production processes. With the addition of sensors for hydrides and hydrogen chloride, Sensorix now offers a complete range of gas sensors for the semiconductor industry to support the world’s supply of electronics”, said General Manager Dr. Andreas König.
